Patented Dec. 1, 1931 STATE PATENT O CE] WILLIAM STEWART IBELLHOUSE, on MANCHESTER, nnetnnn, AssIenonfTo THE nine COTTON srmnnns & DOUBLERS ASSOCIATION LrMI nn, on ivmivcnns'rnn. ENGLAND WINDING MACHINE Application filed August 26, 1929, Serial No. 388,537, and in GreatBritain November 19, 1928;

The invention relates to yarn or thread winding machines of the type in which a large number of ends of the yarn or thread are wound simultaneously parallel side by side in tape form, fiat without twist on to a tube or bobbin at a single operation from which they can be unwound together for lapping on to wire for insulating purposes.

In the winding of yarn or thread in this parallel form on to spools or bobbins, great diificulty has been experienced in retaining the several threads in their flat parallel formation after an end breaks duringthe operation of winding back from the bobbin an 16 piecing up the broken end.

According to the invention the machlne is constructed with a winding back mechanism comprising one or more vertically movable drop fingers fitted to slide on vertical. rods to take up the slack of the ends during piecing up and a stop or knock off mechanism applied to every thread to stop the rotation of the winding head on the breakage of any one thread.

The invention will be fully described with reference to the accompanying drawings in which a machine is shown capable of winding as many as thirty threads simultaneously on to a spool or bobbin.

Fig. 1 is a front elevation of winding frame showing the invention applied thereto.

Fig. 2 is an end elevation.

Fig. 3 is a plan.

Fig. 4c is an end elevation of the winding 35 back mechanism.

Fig. 5 is a plan of Fig. 4:. The machine comprises a winding head of known construction of which the winding spindle A is shown, a winding back mecha-' nism B to take up the slack of the threads when unwound from the spool during piecing up, disposed in front of the machine adjacent to the spool or bobbin spindle A, a stop or knock off mechanism D applied to every thread, combs or reeds C to separate the ends as they come from the cones, a vertical creel E at one side of the frame to carry the cones of yarns F and drag guides G therein for each cone to apply a tension separately to each thread. Or instead of a creel E with cones of the yarn be unwound from cops or pirns h on spindle H.

r The winding head (not shown) is of known construction with a spool or bobbin spindle A, a driving clutch and a knock off handle a. r

The winding back mechanism B comprises one or morevertical rods 6 (preferably three) upon each of which isfitted a vertically mov-' able drop finger 6 free to move up and down and normally held in position at the top of the rod 6 by'a spring catch 6 from which it can be readily released. When winding back to find a broken thread which has run on to the spool at A. the parallel threads are drawn back in a bunch and placed beneath one or more of the drop fingers b which are released singly from their catches b and take up the slack of'the threads in zig-zag form without displacing the relative parallel position of the threads. Short horizontal rods b are placed between'the vertical rods 6 to support the yarn and between each pair a drop finger carries it down as it is unwound. The rods 6 are fitted into a pivoted frame and are normally turned out of the path of the yarn.

The stop mechanism D disposed between the comb or reed C and the winding back mechanism comprises two constantly rotating rollers d, al across which the threads travel and a plurality of looped drop wires 0Z which are hung one one each thread over the nip of the rollers d, 03 The roller 03 is journalled in movable bearings to permit it to move laterally and connected by a rocking lever d and wire d with the knock off handle a. On the falling of any drop wire d consequent upon the breaking of a thread it is. drawn between the rollers d, al displacing the roller 03 laterally against the locking lever 03 and 7 thread and a number of guide pins 9 at the end to direct the threads to the separating comb or reed C.

Instead of or in addition to the creel E spindles H may be placed at the end of the machine to hold cops or pirns it.

What I claim as my invention and desire to protect by Letters Patent is 5 1. A winding machine constructed with a winding spindle stop mechanism, vertical 1y movable drop fingers, vertical rods upon which the drop fingers slide and spring. catches on the vertical rods to normally hold 10 the drop fingers at the top of the rods disposed between the winding spindle and a stop or knock oil mechanism by which the slack of the yarn or threads is taken up during the operation of winding back from the spool or.

15 bobbin and piecing up the broken end.

2.- In a winding frame a winding back mechanism comprising one or more vertically movabledrop fingers fitted to slide on vertical rods and normally held in position at the" :0 top of the rods by spring catches;

3. A winding machine comprising in combination a winding spindle, a stop mechanism, vertically movable drop fingers, vertical rods upon which the drop fingers slide and spring catches on the vertical rods to normally hold the drop fingers at the top of the rods all disposed between the winding head and the stop mechanism.

In testimony whereof I have hereunto set 5 my hand this 16th day of August, 1929;

WILLIAM S. BELLHOUSE.
